Experimental determination of the Dalitz plot for positronium decay using the J-PET detection system

Magdalena Skurzok, Steven D. Bass, Kamila Kasperska +37

We present the first measurements of the Dalitz plot for ortho-positronium annihilation to three photons. Our measurements, accurate to about 3% statistical and 2-3% systematic unc…
